20 types and scope of accidents | Knowledge

Refers to personal injury accidents caused by the inertial force of an uncontrolled object. Damage caused by falling objects, rolling stones, hammering, chipping, chipping, bruises, etc., does not include objects such as explosions, main machinery, vehicles, lifting machinery, collapse, etc.

Refers to the mechanical injury accident caused by the motor vehicle of the enterprise. For example, accidents such as squeezing, pressing, crashing or overturning of a motor vehicle during driving, accidents caused by getting on and off the vehicle during driving, riding a mine car or flying a car, and vehicle transportation hooks and sports car accidents.

Refers to the damage caused by mechanical equipment and tools such as twisting, smashing, touching, cutting, cutting, etc. If the workpiece or the tool flies out of the wound, the chip hurts the person, the hand or the body is caught, the hand or other parts are injured by the cutter, and the rotating mechanism is wrapped around. Common mechanical equipment that hurts the human body includes: belt conveyor, ball mill, driving, winch, drying car, air hammer, lathe, roller machine, sand mixer, screw conveyor, pump, molding machine, sausage machine, crusher, push Coke machine, oil press, vulcanizing machine, unloading machine, centrifuge, mixer, wheel mill, felt spreader, drum screen, etc. Except in the case of vehicles and lifting equipment.

Refers to mechanical injury accidents caused by lifting work. It includes mechanical damage caused by various lifting operations, but does not include electric shock, damage caused by brake failure during maintenance, and falling fall caused by getting up and down the cab.

Refers to the current flowing through the human body, causing physical injury accidents. Suitable for electric shock and lightning damage. For example, the human body is in contact with the metal casing of the device or the temporary line of the exposed body, the hand-held electric hand tool for leakage; the lifting device accidentally touches the high-voltage line or the induction power; the lightning strike damage; the electric shock falls and other accidents.

Refers to an accident caused by a large amount of water entering the lungs through the door and nose, causing obstruction of the airway, causing acute hypoxia and suffocation. It is suitable for water accidents caused by ships, drainage, and facilities during navigation, parking, and operation.

Refers to strong acid, strong alkali splashing to the body caused by burns, or burns caused by fire, burns caused by high temperature objects, skin damage caused by radiation. Suitable for burns, burns, chemical burns, radiation damage, etc. Does not include burns caused by electric burns and fire accidents.

Refers to a corporate fire accident that causes injury or death. Not applicable to fires caused by non-business reasons, such as residents' fires spreading to businesses. Such accidents are in the accidents counted by the fire department.

Point out the injury accident caused by the difference in dangerous gravitational potential energy. It is suitable for scaffolding, platform, steep wall construction and other fall above the ground. It is also suitable for the situation where the mountain ground is stepping into the hole, pit, ditch, lifting mouth and funnel. However, the fall of the other conditions is excluded. If it is working at a high place, it should be an electric shock accident due to electric shock and fall, and it cannot be divided according to the height.

Refers to the collapse of buildings, structures, and piles, as well as accidents caused by landslides. It is suitable for collapse caused by unreasonable design or construction, as well as collapse accidents caused by earth and rock. If the building collapses, the scaffold collapses, and the collapse of the earth and stone when digging trenches, pits, and holes. It is not suitable for mine roofing accidents or collapse accidents caused by explosion or explosion.

Refers to the collapsing of the working face of the mine and the side wall of the roadway due to improper support and excessive pressure, which is called a piece gang; the roof is collapsed into a roof. The two often occur at the same time, referred to as the top piece. It is suitable for collapse accidents caused by mining, underground mining, excavation and other tunnel operations.

Refers to accidents caused by accidental water sources during mine, underground mining or other tunnel operations. Applicable to accidents involving water inrush in wells and aquifers, underground water-bearing zones, karst caves or in contact with flooded roadways and surface waters. Not applicable to ground water damage accidents.

Refers to casualties caused by shooting operations during construction. Suitable for all kinds of blasting operations. Casualties caused by shooting operations such as quarrying, mining, coal mining, mountain opening, road repairing, and demolition of buildings.

It refers to the combination of flammable gas, coal dust and air to form a mixture that reaches the burning limit, and a chemical explosion accident caused by contact with the fire source. It is mainly suitable for coal mines, and is also suitable for occasions where air does not circulate, gas and coal dust accumulate.

Refers to explosion accidents that occur during the production, transportation, and storage of gunpowder and explosives. Applicable to the chemical explosion of gunpowder and explosives in the process of batching, transportation, storage and processing, due to vibration, open flame, friction, static electricity, or thermal decomposition of explosives, storage time is too long or excessive drug accumulation occurs. The accident, as well as the smelting of gold, the waste disposal is not clean, and the explosion caused by gunpowder or explosives remains.

Refers to a physical explosion accident in the boiler. Applicable to steam boilers (hereinafter referred to as boilers) with working pressure and large dry 0.7 meter atmospheric pressure (0.07 MPa), water, but not applicable to railway locomotives, boilers on ships, train power stations and ship power stations. Boiler.

A container (short for a pressure vessel) refers to a pressure-tight device that is relatively prone to accidents and has a high risk of accidents. The explosion of the container is a gas explosion caused by the rupture of the pressure vessel, that is, a physical explosion, including the flammable liquefied gas contained in the container, which evaporates immediately after the container is ruptured, and is mixed with the surrounding air to form an explosive gas mixture, which is generated when the fire source is encountered. Chemical explosion, also known as the second explosion of the container .

Accidents that do not belong to the above explosions are classified as other explosions, such as:

Refers to people who are exposed to toxic substances, such as accidentally eating poisonous foods or breathing poisonous gases, or working in unventilated places such as abandoned tunnels, dark wells, culverts, underground pipes, etc., because of the lack of oxygen, sometimes sudden The accident of fainting or even death is called suffocation. The two phenomena are combined. It is called poisoning and suffocation. It is not suitable for accidents caused by pathological changes such as poisoning and asphyxia, nor for death caused by occupational diseases caused by chronic chronic poisoning.

Any accident that does not fall into the above-mentioned injuries is called other injuries, such as sprains, falls, frostbite, beast bites, nails and so on.
